Which country has such weird copyright laws?

I don't think we have LGPL code in the kernel, but of course I can be
wrong here.
Anyway, NVidia has binary driver being a kernel component and XFree86
driver. While XFree86 driver may or may not be subject to X11 license,
the kernel part (an object file which is then linked to a kernel module
glue code) does not seem to be derived from kernel code.

Still, LGPL has nothing to do with it. The kernel code is licensed
under version 2 of GPL (or maybe later version, but there isn't any).

Having or not having money has nothing to do with it either.

Kernel behaviour is not related to legal issues.

Forget it. The kernel itselt can't force anyone to do anything. That is
the license that matters.
BTW: Of course, vendors are free to produce drivers for their hardware.
Have you seen such a closed-source driver which was working correctly?
I haven't.

IANAL, but I'd assume a patch doesn't change the license for a product
(a file etc), unless stated otherwise.

A module has to be linked when it's loaded. But it, of course, doesn't
matter - the GPL doesn't prevent you from linking GPL code to anything
you want, unless you want to distribute such a beast.
